PROFILING METHOD Russian patent published in 1998 - IPC

FIELD: machine engineering, namely process of profiling parts by cutting tool. SUBSTANCE: method allows to profile parts with deep recesses and large inclination angles of contour. At profiling rotation axis of part and template is normal relative to pivot axis of rocker arm and coaxial with its axis. Template is secured between part and pivot axle, its contour and parameters are selected according to next expressions: h = l•tgγ; , where L is distance between pivot axis of rocker arm and contact point of tool and contour of part cross section, mm; l is distance between pivot axis of rocker arm and point of contour of cross section of template, mm; H is depth of recess of part contour, mm; h is depth of template contour, mm; α - is inclination angle of part profile; β - is inclination angle of template profile; γ - is angle of rocker arm pivoting. EFFECT: enhanced quality of profiled parts with deep recesses. 2 cl, 3 dwg
